Abstract
A method includes recording a first video stream characterized by a first value of a first quality characteristic. The method includes determining that the first video stream satisfies a trigger criterion. The trigger criterion characterizes a threshold amount of video content change information. The method includes, in response to determining that the first video stream satisfies the trigger criterion, obtaining a second video stream characterized by a second value of a second quality characteristic. The second video stream includes scene information also included in the first video stream. The second value of the second quality characteristic is indicative of a higher quality video stream than the first value of the first quality characteristic. The method includes generating a third video stream by adding information from the second video stream to the first video stream. The third video stream corresponds to a higher quality version of the first video stream.
